BOUZO, C. A  and  LENSCAK, M. P. Análisis experimental del efecto de cambios estructurales en invernaderos con techo a dos vertientes. FAVE. Secc. Cienc. agrar. [online]. 2018, vol.17, n.1, pp.7-20. ISSN 1666-7719.

An experimental analysis of a two-slope greenhouse was carried out, to which dimensional modifications and design of the roof windows were made. Were compared the wind speed (m s^-1), air flow rate (m³ h^-1), air temperature (ºC) and vapor pressure deficit (kPa) in two greenhouses called here CMT and CMA. The work was developed in Goya, Corrientes, Argentina (29º 02'S, 59º 10'W) in the year 2016 in february, march and november months. A better micro-meteorological condition was observed in the CMA greenhouse, since it had a lower daytime internal temperature, higher wind speed, air flow and consequently a greater ventilation-rate. The results are discussed based on the dimensional and design differences of the greenhouses taking into account the results of other research works.
